摘要
以巨尾桉嫩枝为插穗,分别经吲哚丁酸和奈乙酸不同浓度溶液浸泡处理后,插入30%~100%持水量的基质,观察其成活率。结果表明,植物生长调节剂浓度为400~800 mg/L和基质持水量为田间持水量87%左右,能显著提高桉树扦插成活率;将2种植物生长调节剂混合使用,对插穗生根成活未产生抗药性,此外,扦插后的圃地管理也很重要。
This paper studied the survival rate of Eucalyptus grandis X E. urophylla cuttings dealing with different concentrations of NAA and IBA in matrix holding 30% - 100% water content. The results showed that 400 -800 mg/L of the growth regulator concentration and 87% of the water-holding capacity could improve the survival rate significantly, that the mixture of NAA and IBA could not produce any resistance to the rooting and survival of the cuttings, and that the management of the cuttings was also important.
